IMPROVEMENT IN il.L'UTIN'G-MACIN'ES The Schedule referred to in theseLetters Patent and making part of the same.

Be it known that I, HENRY B. ADAMS, of the city, county, and'State ofNew York, have invented a new and useful Improvement inFluting-Maehines, and that the following is a full and clear descriptionthereof', reference being had to the annexed drawings, of which- Figure1 represents a front view of a machine containing my improvement, and

Figure 2, an end view.

Heretofore, iuting-ma'chines were made of two fluted revolving rollers,veither both in fixed bearings, or the lower one in fixed bearings, andthe upper one hung in aframe, which was capable of being lowered andraised, either by set-screws, or by hand-levers.

Both the set-screws, as well as the hand-levers, involved a great lossof time of the operator, as it was necessary for him to use one of hishands to raise or lower the upper roller, afact which often proveddetrimental to the goods, if said goods were kept too long in contactwith the hot rollers.

In order to avoid this danger, and provide an instantaneous motion forthe separation of the two {iut-ed rollers, I arrange the upper one, a,in fixed bearings in a frame, Yb, andthe lower one, c, in bearings whichare `attached to a frame, (l, and this frame d lis made to slide up anddown, by having a stern, e, in the centre of its lower side, which isguided straight up and down in a box, f, xed to the main frame b, andthe motion of raising and lowering the frame 1, and its roller c, isobtained by a lever, g, whose fulerum is at hf, in about the centre of.the said lever.

Both ends of the said lever g are arranged with slots, as olearlyshownin fig.' 1, to receive a strap, k, which reaches down to the floor,where, by means of a loop,

or treadle, attached thereto, the lever can be worked by the operatorsfoot.

This lever g also contains a projection at its upper edge, which entersthe guide-box f, and vis capable of raising the slide cl, and its rollerc, by abutting against the stem e.

The operator can attach'the strap k to either end of lever y. If hefixes the said strap to the left-hand end, as shown in iig. 1, there isa spring, Z, required, to bea-r upon the opposite end, which springserves to force the left-hand end of the lever up, and so lift the lowerroller. Then the operator separates the two rollers, by pulling thestrap downby his foot, and, if he fixes the said strap to the 1ight-handend of leverg, then the spring l must be turned sidewise, out of contactwith the lever. Then the operator raises the lower roller, by forcingthe strap down by his foot, and he separates the two rollers from eachother by lifting his foot, as the lower roller, and its slide fl, willdrop by their own gravity.

l In both cases the'mo'tion is instantaneous, and performed by theoperator without taking his hands off the work.

Having now fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is-

The lower movable roller c, hung in a slidin g frame, (l, and thedouble-ended lever g and strap k, arranged and operated substantially asdescribed.
